During the ferroptosis and mitochondrial stage of apoptosis, a mitochondria-specific phospholipid, cardiolipin (CL), undergoes peroxidation. MitoCLox is a mitochondria-targeted fluorescence probe that allows monitoring of this process in vivo.
MitoCLox consists of the BDP 581/591 fluorophore carrying a diene-containing moiety (C11) and linked with a triphenylphosphonium (TPP) residue via a long flexible linker with two amide bonds. MitoCLox is similar to MitoPerOx but has a longer linker and contains two (vs. one in MitoPerOx) peptide bonds. The flexible linker of MitoCLox mimics the SS-20 peptide (Phe-D-Arg-Phe-Lys-NH2), making the indicator specific for cardiolipin. The linker also increases the cellular permeability of MitoCLox due to additional positive charges.
The oxidation of the diene in MitoCLox results in a substantial increase in the fluorescence emission at 520 nm and a decrease in the initial fluorescence at 590 nm of the BDP 581/591 fluorophore. Thus, the oxidation of MitoCLox could be measured either as a decrease of absorbance at 588 nm or as an increase of fluorescence emission in the ratiometric mode at 520/590 nm [1].
MitoCLox is accumulated in the mitochondria of living cells. Maximal accumulation of MitoCLox in the cells is reached in 45-60 min. After removing MitoCLox from the medium, the fluorescence of the cells slowly decreased and reached 50% of the maximum in approximately 1 h. The recommended working concentration of MitoCLox is 100-200 nM [2].
